With the continuous improvement of the informatization level of natural resource land supervision,higher requirements have been put forward for the deterministic description of spatial data of natural resource land.In order to finely process the complex spatial rela-tionships of targets with holes in natural resource land data,this paper combines the 25 inter-section model to decompose the targets with holes into multiple simple subsets or point sets.By utilizing the connections between known objects or point sets,the topological relationships of targets with holes are accurately expressed.Based on ArcPy,the precise expression of natural resource land text data to entity spatial data is achieved.The results show that the technical implementation measures proposed in this article have the characteristics of high automation and strong fault tolerance compared to others,and can achieve high-quality and efficient con-version of two types of data,thereby significantly improving the efficiency of natural resource land reporting and land use analysis work.
